To meet a U.S. Postal Service requirement, employees' footwear must have a coefficient of static friction of 0.5 or more on a specified tile surface. A typical athletic shoe has a coefficient of 0.781. In an emergency, what is the minimum time interval in which a person starting from rest can move 3.41 m on a tile surface if she is wearing the following footwear? (a) footwear meeting the Postal Service minimum x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error, s (b) a typical athletic shoe x Your response differs from the correct answel by more than 10%. Double check your calculations, s
